This is back in the days when gas station attendants pumped gas for you, and gas was only 40¢ per gallon. It’s a hot summer day. Note that the station is on a superhighway, so we get customers from all over the world, and our orders can vary widely.

A customer drives up to the pump, but will not roll down his window. He wildly gesticulates 5 fingers at me.
Me (speaking loudly at the window): Five dollars or five gallons, sir.
Customer: continues to wave his hand at me
Me: Five dollars or five gallons, sir?
Customer: continues to wave his hand at me
Me: Five dollars or five gallons, sir?
Customer finally rolls down the window: Five dollars
He then quickly rolls the window back up.
Me (smugly): Regular or high-test, sir?
